https://bz.apache.org/bugzilla/attachment.cgi?id=35682&action=editClass to read template excel sheet, modify and encrypt it and return encypted
excel sheet as byte array.
Trying to encrypt excel workbook with password and send byte array to an
emailer class that mails the file. Cannot figure out how to do this without
writing a file to some location.
While attempting to work around saving a file somewhere I encountered this
error:
Exception in thread "main" java.lang.Exception:
org.apache.poi.openxml4j.exceptions.OpenXML4JRuntimeException: Rule M2.4
exception : this error should NEVER happen! If you can provide the triggering
file, then please raise a bug at
https://bz.apache.org/bugzilla/enter_bug.cgi?product=POI and attach the file
that triggers it, thanks!
at excelTesting.ExcelEncryption.doReport(ExcelEncryption.java:308)
at excelTesting.ExcelEncryption.main(ExcelEncryption.java:317)
Attached is the class that is getting the error.
